Answer:

Any line passing through the origin represents a proportional relationship

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and<u> the line passes through the origin</u>

therefore

Any line passing through the origin represents a proportional relationship

You can tell a graph is proportional if the points form a single line and that line passes through the origin. The relationship between input and output figures will also remain the same throughout.

The diameter of a bacterium called Spiral is 0.000015 meter. What is this

enyata [817]

Hey there!

When we put a number in scientific notation, we want the first number to be at least 1 and less than 10. There must be a digit from 1-9 in the ones place.

With the number 0.000015, we can move the decimal place 5 places to the right and we have 1.5, which is more than one and less than ten.

Because we moved the decimal place 5 places to the right, 1.5 is multiplied by 10 to the power of -5.

The 5 is the number of places the decimal is moved, and the negative sign is because we moved it to the right.

10^(-5) is the same as 0.00001, just for context.

So, 0.000015 meters in scientific notation is 1.5 x 10^(5) meters.

Hope this helps!
